Using transmission electron microscopy, we characterised the structures of the boundary caused by the interactions between different {1 0 1 2} twin variants that share the same [ 1 1 2 0] zone axis in a deformed magnesium alloy. We found that the twin- twin boundaries can adopt the habit planes that are parallel to the (0 0 0 2) basal plane or the (1 0 1 0) prismatic plane or the (1 0 1 2) twinning plane of the interacting twins. To investigate the formation mechanism of various twin- twin boundaries, we also performed atomic simulations. The results indicate that the formation of a twin- twin boundary may be related to the reaction of twinning disconnections that glide on the basal- prismatic planes of the interacting twins.
